The X- Bionic Merino leggings are thermal underwear dedicated to those ladies who appreciate natural materials and their properties. Saxon merino wool, from which the leggings are made, helps to maintain the optimum body temperature (cools or warms depending on the need) and is a quick-drying material, which, combined with the intelligent solutions known from X-Bionic products, creates underwear perfect for sports at low temperatures.

Products of the Merino line are characterised by low compression, but offer a wide range of movement and extremely pleasant, gentle warmth - they are indispensable when practising sports in extremely cold temperatures.

The Caleons feature revolutionary zonal compression and the patented 3D Bionic Sphere® system with ThermoSyphon® technology to optimise performance through improved cooling. The Sweat Traps® system captures perspiration and promotes temperature balance through targeted evaporation, while the AIR-CONDITIONING CHANNEL® 4.0 channel system provides intensive body ventilation and wicks moisture away. Thanks to these technologies, the body temperature is maintained at an optimal 37°C and the muscles receive support and are ready for superhuman effort.

The INNERLAP AIRCONDITIONING ZONE® located on the inner side of the thigh, which is less reactive to the cold and sweats more, allows for better air exchange and faster wicking, providing intensive ventilation. The EXPANSSIONKNEE® technology protects the knees from cooling, even when bent, and thanks to the finely woven mesh AirConditioningSpot at the back of the knee, perspiration evaporates very quickly.

The leggings' legs finished with Aktiv-Bund tape and the functional cut of the IDEO-Waistband® keep the underwear in place, guaranteeing a perfect hold without slipping. The ISO-Calfpad zone, on the other hand, consisting of corrugated channels that are located on the calf muscles, stores air to prevent chilling, especially after a prolonged stop.

Calfpads deal perfectly with unpleasant odours thanks to SKIN NODOR® fibres, which prevent the proliferation of bacteria by releasing skin-neutral ions. The new product generation X-Bionic 4.0 is the first to offer the ultra-high quality of Retina® - an exceptionally tight knit in which the thermoregulatory zones can operate with the utmost precision.
